Landscape exploitation and middle-distance supply of mudbricks for the Carthaginian rampart of Qart Hadasht (Spain)

Founded in 228/227 BCE, the Carthaginian city of Qart Hadasht in southern Spain became the principal Punic political centre and military port in the western Mediterranean. Its defensive architecture featured a robust casemate wall composed of an outer sandstone face and inner mudbrick walls. Here, the authors present the geoarchaeological analysis of the earthen materials used in the construction of this wall. The results reveal differences in composition and provenance between mudbricks and mud mortars, with the former sourced across distances of 7–8km, highlighting the detailed knowledge of hinterland resources and complex political organisation involved in the wall’s construction.
